Annoying at hell.....I was on the phone with Dish Network disputing a charge when someone from this number kept buzzing in.  First it was listed as Tucson 1-520-333-1004 then two minutes later Richard 1-520-333-1004, then about 20 minutes later (yes, still on the phone with Dish Network) "Tucson" and two minutes later "Richard."  A few days earlier I had answered the call and it was some sort of recording.

This is a telemarketing recording for a money making scheme but they never disclose the name of the company. If you call 1-877-850-2280 (an automated number) you are supposedly removed from the calling list

left a message to much noise on the other end could not make out what was sais.
